Control unit 121 carries out calculation process according to the instruction of various programs.Specifically, control unit 121 is based in constituent parts The view data of the unit data pattern 31 formed in storage zone UA judges whether that unit data can be read（Unit position String）, or unit data read based on the view data of unit data pattern 31（Unit bit string）, or based on non-in data The address schemes AP formed in storage zone NA view data reads unit storage zone UA positional information, or is sentencing Break as unit data can not be carried out（Unit bit string）Reading in the case of generation error data, or make to be taken by view data The data etc. of the view data that obtains of portion 110 or various generations are stored in storage part 122, or by read-out units According to（Unit bit string）With reference to come recover in data storage media 1 record, preserve data.
Storage part 122 is except the storage zone SA to being obtained by view data obtaining section 110（Unit storage zone UA）'s Outside view data is stored, also by the view data based on the unit data pattern 31 formed in unit storage zone UA And the unit data read（Unit bit string）The unit storage zone UA's read with the view data based on address schemes AP Positional information associates storage, or by the wrong data generated by control unit 121 and is judged as that units can not be carried out According to（Unit bit string）The unit storage zone UA positional information of reading associate storage.As with such control unit 121 and the control device 120 of storage part 122, general computer etc. can be used.
To reading the record in data storage media 1 using the data readout setup 100 having a structure in which, preserving The methods of data illustrate.Figure 13 is the flow chart for each operation for showing the data read method in first embodiment.
First, when setting data storage media 1 in view data obtaining section 110, view data obtaining section 110 utilizes Scanner section 112 makes data storage media 1 relatively be moved relative to image pickup part 111, and data are preserved successively using image pickup part 111 The storage zone SA of medium 1 constituent parts storage zone UA is imaged, and is obtained comprising constituent parts storage zone UA and right with it The view data of the address schemes AP answered image（S1）.
The scanner section 112 of view data obtaining section 110 by the way that the border pattern 50 of data storage media 1 is identified, So that data storage media 1 relatively moves relative to image pickup part 111, so that unit storage zone UA and corresponding ground Location pattern AP is comprised in reference object region.Thus, at least one unit is included in the image imaged by image pickup part 111 Storage zone UA, corresponding address schemes AP and border pattern 50.
Each view data obtained by view data obtaining section 110 is stored in the storage part 122 of control device 120, Control unit 121 judges whether to be based in unit storage zone UA according to each view data stored in storage part 122 The unit data pattern 31 of formation carries out unit data（Unit bit string）Reading（S2）.Specifically, according to each view data, Judge in the sag and swell 3 for forming the unit data pattern 31 in unit storage zone UA with the presence or absence of breakage etc..
It is being judged as that unit data can be carried out based on unit data pattern 31（Unit bit string）Reading in the case of （S2, it is）I.e. in the case where being judged as that damaged wait is not present in the sag and swell 3 in unit data pattern 31, control unit 121 Unit data pattern 31, which is based on, from the view data reads unit data（Unit bit string）, also, read based on address schemes AP Unit storage zone UA positional information, makes the unit data（Unit bit string）Associated with positional information and be stored in storage In portion 122（S3）.
Unit data is being read based on unit data pattern 31（Unit bit string）When, control unit 121 is protected comprising unit Deposit and virtual grid Gr is defined in the view data of region UA and border pattern 50.Virtual grid Gr is defined as by positioned at 4 The datum mark Cp of the border pattern 50 at angle.Then, control unit 121 judges that the virtual grid Gr's in unit storage zone UA is each It whether there is recess 311 on intersection point PI.For example, it can be made whether to have recess based on the bright dark distribution in view data 311 judgement.
Position " 1 " is mapped by control unit 121 with being determined to have the intersection point PI of recess 311, by position " 0 " and is determined as not The intersection point PI that recess 311 be present is mapped, and thus, reads unit data（Unit bit string）.
Control unit 121 is reading unit data based on unit data pattern 31（Unit bit string）In the case of, to image The border pattern 50 positioned at upper left in data is identified, using the datum mark Cp of the border pattern 50 as index, from positioned at The virtual grid Gr in the direction of its bottom right intersection point PI be on intersection point PI in unit storage zone UA right direction start whether The judgement of recess 311 be present.
On the other hand, it is being judged as that unit data can not be carried out based on unit data pattern 31（Unit bit string）Reading In the case of going out（S2, it is no）I.e. in the case where being judged as having damaged wait in the sag and swell 3 in unit data pattern 31, control Portion 121 processed reads unit storage zone UA positional information based on address schemes AP, also, generation can not carry out unit Data（Unit bit string）Reading the meaning wrong data, wrong data and positional information is associated and is stored in storage part In 122（S4）.
Control unit 121 makes unit data（Unit bit string）Associated with positional information and be stored in it in storage part 122 Afterwards（S3）Or wrong data and positional information is set to associate after being stored in storage part 122（S4）, judge in storage part 122 In whether be stored with and do not judge whether that unit data can be carried out（Unit bit string）Reading view data（S5）, in storage part In the case of the view data is stored with 122（S5, it is）, repeat the later processing of S2.
On the other hand, in the case of not being stored with the view data in storage part 122（S5, it is no）, control unit 121 judges Whether wrong data is stored with storage part 122（S6）, in the case of not being stored with wrong data in storage part 122（S6, It is no）, the unit data that will be stored in storage part 122（Unit bit string）With reference to generation data（Bit string）（S7）.
In generation data（Bit string）When, control unit 121 is based on and unit data（Unit bit string）Associate the position of storage Confidence ceases, and determines unit data（Unit bit string）Binding sequence.Specifically, control unit 121 is using as the line number of positional information Code is used as the first preferential precedence, using column number as the second preferential precedence, makes unit according to the small order of line number code and column number Data（Unit bit string）With reference to.Like this, the data preserved in data storage media 1 can be recovered.
On the other hand, in the case of being stored with wrong data in storage part 122（S6, it is）, control unit 121 is based on the mistake Data output can not read unit data by mistake（Unit bit string）The meaning and unit storage zone UA positional information（S8）.Only To be remembered based on the output of the positional information according to the duplicate of data storage media 1 to generate in unit storage zone UA Record, the unit data preserved（Unit bit string）, then by the unit data（Unit bit string）With the unit stored in storage part 122 Data（Unit bit string）Combine together, the correct recovery of data preserved in data storage media 1 can be carried out.
(second embodiment)
[data storage media]
Fig. 1 is the plan of the schematic configuration for the data storage media for showing second embodiment, and Figure 15 is to show the second implementation The plan of the schematic configuration of unit storage zone in mode, Fig. 3 are show storage zone in second embodiment flat Face figure, Figure 16 are the I-I lines cut-outs in part amplification cut-out end view drawing i.e. Figure 15 of the data storage media of second embodiment End view drawing.
The data storage media 1 of second embodiment possesses：With the first face 21 and relative with first face 21 second Face 22 and the base material 2 being made up of the quartz glass of general square shape shape, by the data content of the data with being preserved（Bit string）'s Physique corresponding to everybody shows the data content of the data（Bit string）Data pattern be formed in the first face of base material 2 In the storage zone SA of the general square shape shape defined on 21.
Arranged in storage zone SA with M rows × N（On M and N, one is more than 2 integer, and another is more than 1 Integer.）The multiple unit storage zone UA of matrix configuration juxtaposition.As shown in figure 3, in this second embodiment, enumerate with 4 rows（M =4）× 6 row（N=6）Matrix configuration juxtaposition 24 unit storage zone UA example be illustrated, still, do not limit In which.
Storage zone SA includes multiple unit storage zone UA and the field between adjacent unit storage zone UA Between trail shape the non-storage zone NA of data.Constituent parts storage zone UA is the region formed with unit data pattern 31, data Non- storage zone NA is the region formed with orientation index pattern 40 and border pattern 50.
Can be in image pickup part 111 described later can camera watch region size（It can be preserved with that can identify in unit The physique of the unit data pattern 31 formed in the UA of region（Recess 311 and convex portion 312）Multiplying power shooting region it is big It is small）Carry out the appropriate size for setting unit storage zone UA.In addition, as long as the non-storage zone NA of data size is being capable of at least shape Into the size of orientation indicatrix case 40, then it is not particularly restricted, still, by using up the non-storage zone NA of data size It is possibly small, so as to increase the ratio shared by the unit storage zone UA in storage zone SA, data can be made Recording capacity becomes big.Now, preferably by the non-storage zone NA of data width WNAIt is set as and the list in unit storage zone UA The physique of position data pattern 31（Recess 311 and convex portion 312）Interval integral multiple it is inconsistent.Thereby, it is possible to clearly Hold the non-storage zone NA of data.
The unit data pattern 31 formed in constituent parts storage zone UA by will be recorded in data storage media 1, The data of preservation be divided into it is multiple after unit data data content（Unit bit string）The recess showed（Hole）311 and convex Portion（It is formed without the part in hole）312 are formed.In this second embodiment, the position " 1 " among the unit bit string of the unit data It is defined as recess 311, position " 0 " is defined as convex portion 312.For example, in fig.15, from upper left towards it is right by Unit bit string as " 1010011101 ... "（Unit bit matrix）The unit data of performance is recorded, is stored in data preservation Jie In the unit storage zone UA of matter 1.Further, the position " 1 " among unit bit string be defined as convex portion 312 and " 0 " be defined as it is recessed Also may be used in portion 311.
Using as the recess 311 of unit data pattern 31 and convex portion 312 by be configured to it is rectangular in a manner of formed in unit In storage zone UA, the matrix configuration of the recess 311 and convex portion 312 is to match somebody with somebody with the unit bit string of unit data is transformed into matrix Configured corresponding to the unit bit matrix postponed.
As the species for the data for recording, preserving in data storage media 1, and it is not specifically limited, for example, can enumerate The view data such as text data, live image or rest image, voice data etc..
Orientation index pattern 40 is to show and the unit data pattern 31 by being formed in constituent parts storage zone UA （Recess 311 and convex portion 312）The unit bit string of performance（Unit bit matrix）The relevant information of orientation pattern, also, For the pattern being correspondingly arranged with constituent parts storage zone UA, it is made up of the recess 41 as physique.Orientation refers to Case of marking on a map 40 shows the unit data pattern 31 with being formed in unit storage zone UA（The unit bit string of unit data）Square Battle array configures relevant information.In illustrated example, orientation index pattern 40 is formed on rectangular unit storage zone UA Left nearby and left lower corner near, orientation index pattern 40 be formed on the position mode be data preservation The positive position of medium 1.Using this as premise, thereby, it is possible to be interpreted as with unit bit string（Unit bit matrix）Corresponding matrix Configuration（From unit storage zone UA upper left towards the matrix configuration of bottom right）Form unit data pattern 31（Recess 311 and convex Portion 312）.In fig. 17 it is shown that everybody corresponding unit data of arrangement and the unit bit string of unit data in the direction of the arrow Pattern 31（Recess 311 and convex portion 312）.
Can be to the unit by being formed in constituent parts storage zone UA as long as orientation index pattern 40 is formed on The unit bit string that data pattern 31 shows（Unit bit matrix）Orientation carry out specially appointed position, do not limit In aforesaid way.Orientation index pattern 40 is preferably formed in by unit storage zone UA and orientation index pattern 40 The global shape of composition is position as the shape without symmetry such as point symmetry, the symmetrical, rotational symmetry of line.For example, such as Shown in Figure 18, unit storage zone UA be shaped as substantially rectangular shape in the case of, orientation index pattern 40 also may be used Think 1 corner among unit storage zone UA 4 corners（It is the corner of upper left in the example shown in Figure 18）'s Nearby and along 1 side（Long side or short side.For positioned at the long side of upside in the example shown in Figure 18）Formed.By that will arrange Column direction index pattern 40 is formed at such position, so as to as described later, be read data storage media 1 is arranged on into data When going out in device 100, storage zone SA can be passed through（Unit storage zone UA）With the image pickup part 111 of data readout setup 100 Position relationship whether readily recognize be positive position.
Further, as shown in figure 19, as long as not damaging imagination life-span or the stability of data storage media 1, then second implements Orientation index pattern 40 in mode can also be different by base materials 2 such as the metallic films that is formed from by chromium oxide etc. component Form.In addition, the shape of orientation index pattern 40, size etc. and be not specifically limited, however, it is preferred to component unit number According to the physique of pattern 31（Recess 311 and convex portion 312）Shape or size it is different.Component unit data pattern 31 and arrangement The shape or size of the physique of cardinal direction marker pattern 40 are different from each other, and thereby, it is possible to according to by data readout setup 100 The view data that image pickup part 111 obtains readily recognizes orientation index pattern 40.
Orientation index pattern 40 can also be formed in unit storage zone UA as shown in Figure 20.In the feelings Under condition, also may be used in storage zone SA in the absence of the non-storage zone NA of data.Thus, the record in data storage media 1 is sought The increase of capacity.
As long as the unit data pattern 31 in second embodiment is made up of i.e. the physique that can optically identify Can, it is not limited to recess 311 and convex portion 312.For example, as shown in figure 21, can also be corresponding by the position " 1 " with unit bit string Insertion hole portion 313 and non-hole portion 314 corresponding with position " 0 " are formed.In this case, orientation index pattern 40 by with unit The same physique of data pattern 31 penetrates hole portion and formed from the viewpoint of the time in the making of data storage media 1 It is preferable.On the other hand, any one of unit data pattern 31 and orientation index pattern 40 are by non-penetrating recess structure Into and another is made up of insertion hole portion and also may be used.As long as such mode, then passing through data readout setup 100 described later （Reference picture 12）Image pickup part 111 obtain data storage media 1 the side of the second face 22 view data when, it is impossible to confirm any one （Unit data pattern 31 or orientation index pattern 40）Presence, therefore, thus, it is possible to readily recognize in data read-out The surface back side reversion of the data storage media 1 set in device 100.
Further, orientation index pattern 40 shows the unit data pattern 31 with being formed in constituent parts storage zone UA The relevant information of orientation, also, show that the positional information of the constituent parts storage zone UA in storage zone SA also may be used. For example, orientation index pattern 40 can also be by physique（Recess 41 and convex portion 42）Performance has been imitated numeral The pattern of braille（Reference picture 5）The pattern formed, the numeral are configured to rectangular each list for expression in storage zone SA The pth row of position storage zone UA juxtaposition（P is more than 1 below M integer.）Arranged with q（Q is the whole of more than 1 below N Number.）Such line number code and column number（p, q）Numeral.Further, in fig. 22, shown using orientation index pattern 40 Unit storage zone UA is positioned at situation as the region of the 04th row 02 row.
In this case, orientation index pattern 40 in the same manner as unit data pattern 31 by representing line number code and row The physique of bit string after the value of numeral 2 of number（Recess 41 and convex portion 42）Composition also may be used.
Border pattern 50 for represent unit storage zone UA and be expert to row upwards via the non-storage zone of data The pattern on other unit storage zone UA adjacent NA border, also, it is formed the constituent parts positioned at general square shape shape Storage zone UA 4 jiaos of outside.By border pattern 50 as formation, so as to pass through data readout setup 100 Image pickup part 111 readily recognizes constituent parts storage zone UA, can carry out recording as multiple unit data patterns 31, preserve The correct reading of data.
In this second embodiment, border pattern 50 is substantially crosswise, also, 4 extended from its intersection point L towards outside The length of 1 pattern 51 among individual pattern 51 ~ 54（Length from intersection point on the bearing of trend of the pattern）Than other 3 The length of pattern 52 ~ 54 is short（Reference picture 6（a））.The border pattern 50 with such shape is formed, so that it is according to conservation zone The juxtaposition order of multiple unit storage zone UA in the SA of domain（From the upper left in Fig. 3 towards the order of transverse direction）90 ° of 90 ° of ground successively Rotation（Reference picture 7）.As described later, record, the data preserved in the data storage media 1 in second embodiment is read When, image pickup part 111 is relatively moved relative to data storage media 1 while obtaining constituent parts storage zone UA image Data.Therefore, whenever carry out image pickup part 111 it is mobile when, all carry out image pickup part 111 position alignment, obtain view data, but It is that border pattern 50 is rotated according to unit storage zone UA 90 ° of 90 ° of ground of juxtaposition order, and thereby, it is possible to one side to make shooting Scan while obtaining view data according to unit storage zone UA juxtaposition order in portion 111.
Further, border pattern 50 is used as other modes（Plane regards shape）Can also be substantially L-shaped（With from benchmark The shape of 2 patterns that point Cp extends to 2 directions, orthogonal）（Reference picture 6（b））, or substantially crosswise is The length of 4 patterns extended laterally from datum mark Cp（Length from intersection point on the bearing of trend of the pattern）Substantially Identical shape（Reference picture 6（c））.
In this second embodiment, the recess 311 of component unit data pattern 31 is the hole shape that plane regards general square shape shape Shape.As long as the size of the recess 311 can optically to identify the size of recess 311 by common photographing element, But in order that in data storage media 1 be able to record, preserve data capacity increase, the recess of unit data pattern 31 311 size can for example be set to below 400nm, be preferable to be set to 100 ~ 250nm or so.
As shown in figure 23, unit data pattern 31 and orientation index pattern 40 are all formed and in storage zone SA The virtual grid Gr of interior setting intersection point PI is overlapping, and border pattern 50 is formed the grid line overlap with virtual grid Gr.More Specifically, unit data pattern 31, orientation index pattern 40 and border pattern 50 are formed, so that with unit data pattern 31 （Recess 311）The mode overlapping with virtual grid Gr intersection point PI with the datum mark Cp of each of orientation index pattern 40 The datum mark Cp and virtual grid Gr of border pattern 50 grid line overlap and it is located at adjacent intersection point PI（In fig 23 upper The upward adjacent intersection point PI in lower section）Substantially among.Here, the benchmark of unit data pattern 31 and orientation index pattern 40 Point Cp is the central point during the plane of the physique of component unit data pattern 31 and orientation index pattern 40 regards, border The datum mark Cp of pattern 50 is the intersection point L of substantially crosswise.As long as further, at least with the datum mark Cp of unit data pattern 31 with The mode that virtual grid Gr intersection point PI is overlapping is formed, the datum mark Cp of orientation index pattern 40 and border pattern 50 It is overlapping with virtual grid Gr intersection point PI also can, with virtual grid Gr grid line overlap but it is not overlapping with intersection point PI also can, With which of virtual grid Gr intersection point PI and grid lines be not overlapping may be used yet.
In the data storage media 1 of the second embodiment with above-mentioned structure, the number of the data record, preserved According to content（Bit string）By the unit data pattern 31 formed in storage zone SA constituent parts storage zone UA（It is configured to matrix Shape, recess 311 as physique and convex portion 312）Performance.Moreover, it is correspondingly formed into constituent parts storage zone UA For the physique in unit data pattern 31（Recess 311 and convex portion 312）Configuration sequence index orientation index Pattern 40, therefore, by identifying the orientation index pattern 40, so as to correctly identify the order for reading data, energy It is enough correctly to recover the data.

(the 3rd embodiment)
[data storage media]
Fig. 1 is the plan of the schematic configuration for the data storage media for showing the 3rd embodiment, and Figure 29 is to show the 3rd implementation The plan of the schematic configuration of unit storage zone in mode, Figure 30 are show storage zone in the 3rd embodiment flat Face figure, Figure 31 are the I-I lines cut-outs in part amplification cut-out end view drawing i.e. Figure 29 of the data storage media of the 3rd embodiment End view drawing.
The data storage media 1 of 3rd embodiment possesses：With the first face 21 and relative with first face 21 second Face 22 and the base material 2 that is made up of the quartz glass of general square shape shape and it is formed at what is set on the first face 21 of base material 2 The sag and swell formed in storage zone SA.
Arranged in storage zone SA with M rows × N（On M and N, one is more than 2 integer, and another is more than 1 Integer.）The multiple unit storage zone UA of matrix configuration juxtaposition.As shown in figure 30, in the third embodiment, enumerate with 8 rows （M=8）× 6 row（N=6）48 unit storage zone UA of matrix configuration juxtaposition（UA1~UA48）Example be illustrated, But it is not limited to which.
Storage zone SA includes multiple unit storage zone UA and the field between adjacent unit storage zone UA Between trail shape the non-storage zone NA of data.In the third embodiment, constituent parts storage zone UA is formed with as bumps Unit data pattern 31, dummy pattern 32 and the region for differentiating pattern 33 of construction, the non-storage zone NA of data are formed with ground Location pattern AP and border pattern 50 region.
Can be in image pickup part 111 described later can the size of shooting area suitably set unit storage zone UA's Size.It is in addition, as long as the non-storage zone NA of data size is can at least form address schemes AP size, then not special Limitation, still, by making the non-storage zone NA of data size small as much as possible, so as to make the list in storage zone SA Ratio increase shared by the storage zone UA of position, the recording capacity of data can be made to become big.
The unit data pattern 31 formed in constituent parts storage zone UA by will be recorded in data storage media 1, The data of preservation be divided into it is multiple after unit data data content（Unit bit string）The recess showed（Hole（hole）） 311 and convex portion（In the absence of the part in hole）312 are formed.In the third embodiment, among the unit bit string of the unit data " 1 " is defined as recess 311, and " 0 " is defined as convex portion 312.For example, in Figure 29, by " 1010011101 ... " from upper left Such unit bit string（Unit bit matrix）The unit that the unit data of performance was recorded, be stored in data storage media 1 preserves In the UA of region.Further, " 1 " among unit bit string is defined as convex portion 312 and " 0 " is defined as recess 311 and also may be used.
As the species for the data for recording, preserving in data storage media 1, and it is not specifically limited, for example, can enumerate The view data such as text data, live image or rest image, voice data etc..
In constituent parts storage zone UA, the region formed with unit data pattern 31 is data area DTA, and unit preserves The region beyond the DTA of data area in the UA of region is nominal region DMA.Formed with dummy pattern in nominal region DMA 32。
Dummy pattern 32（Recess 321）The gross area relative to the nominal region DMA gross area ratio（Hereinafter referred to as " area density of dummy pattern 32 ".）With unit data pattern 31（Recess 311）The gross area relative to data area DTA's The ratio of the gross area（Hereinafter referred to as " area density of unit data pattern 31 ".）It is substantially the same.Specifically, dummy pattern 32 area density is 90 ~ 110% or so, preferably 95 ~ 105% or so of the area density of unit data pattern 31.It is illusory The area density of the area density of pattern 32 and unit data pattern 31 is substantially the same, thus, as described later, makes utilizing When being handled with the impressing of data storage media 1 to make the duplicate of the data storage media 1, transfer figure can be prevented The pattern defect of case.
The shape of unit data pattern 31 and dummy pattern 32（Plane regards shape）It is preferable to be essentially the same as each other.Such as Shown in Figure 29, the recess 311,321 for forming the unit data pattern 31 in the 3rd embodiment and dummy pattern 32 regards for plane Generally square hole shape.As long as the size of the recess 311 of unit data pattern 31 is that can utilize common photographing element The size of recess 311 is optically identified, still, in order that the data for being able to record, preserving in data storage media 1 Capacity increases, and the size of the recess 311 of unit data pattern 31 can for example be set to less than 400 μm, be preferable to It is set to 100 ~ 250 μm or so.The size of the recess 321 of dummy pattern 32 is simultaneously not specifically limited, however, it is preferred to and unit The size of the recess 311 of data pattern 31 is substantially the same.The recess 311 of unit data pattern 31 and the recess of dummy pattern 32 321 shape and size are essentially the same as each other, and thus, are being made using having used the impressing of data storage media 1 to handle During the duplicate of the data storage media 1, it can prevent to transfer the pattern defect of pattern.
In the third embodiment, unit data pattern 31 and illusory figure can be formed in a unit storage zone UA Case 32.Moreover, in unit data pattern 31（Recess 311）With dummy pattern 32（Recess 321）With what is be essentially the same as each other In the case of shape and size, it is difficult to differentiate unit data pattern 31（Data area DTA）With dummy pattern 32（Nominal region DMA）Border.Therefore, in the third embodiment, in everybody corresponding multiple unit data patterns 31 of the bit string with data Among the corresponding unit data pattern 31 in last position with the bit string of data（Recess 311 or convex portion 312）With dummy pattern 32 Between formed with pattern 33 is differentiated, the differentiation pattern 33, which plays, clearly differentiates unit data pattern 31（Data area DTA） With dummy pattern 32（Nominal region DMA）Border effect.
Such differentiation pattern 33 can be configured to shape and size and unit data pattern 31（Recess 311）With it is illusory Pattern 32（Recess 321）Different recess 331, reliably to play the effect.In the third embodiment, pattern 33 is differentiated Shape（Plane regards shape）For long dimensional directions along row to substantially rectangular shape.Thus, filled in data read-out described later When reading data from data storage media 1 in putting 100, unit data pattern 31 optionally can be only extracted, can be correctly Read the data preserved in data storage media 1.
Further, many of the data preserved in data storage media 1 includes expression data file in its data content Terminal controlling symbols（EOF）, therefore, in the case where not setting differentiation pattern 33 in addition by the end with representing data file Pattern corresponding to the controlling symbols at end also may be used as above-mentioned differentiation pattern 33.In addition, by a pair symbol same with the controlling symbols Carry out pattern corresponding to the bit string after 2 values be used as above-mentioned differentiation pattern 33 also can, be otherwise determined that the end for representing data file End 2 values after bit string and pattern corresponding with the bit string also may be used as above-mentioned differentiation pattern 33.Further, implement the 3rd In mode, as long as at least one kind of differentiation pattern 33 is formed, still, by multiple patterns（For example, shape and size and units According to pattern 31（Recess 311）With dummy pattern 32（Recess 321）Different patterns（Recess 331）And with representing data file This 2 kinds of patterns of pattern corresponding to the controlling symbols of terminal）Be formed as above-mentioned differentiation pattern 33 also may be used.
In the third embodiment, the address schemes AP formed in the non-storage zone NA of data is by storage zone SA The recess 41 and convex portion 42 that interior constituent parts storage zone UA positional information is showed are formed.In the third embodiment, The address schemes AP for representing the positional information of the constituent parts storage zone UA in storage zone SA is by recess 41 and convex portion 42 The pattern of numeral braille has been imitated in performance（Reference picture 5）The pattern formed, the numeral are expression constituent parts conservation zone The pth row of domain UA juxtaposition（P is more than 1 below M integer.）Arranged with q（Q is more than 1 below N integer.）So Line number code and column number（p, q）Numeral.In Figure 29, it is position to be demonstrated by unit storage zone UA using address schemes AP In situation as the region of the 04th row 02 row.
